BOOT AND SHOE.

Specification of Letters Patent.

ratented may 21, 1907.

Application filed May 19,1906. Serial No. 317,768.

which in use will effectively secure the over' shoe in place againstpossibility of accidental removal.

The main object of the invention is the production of an attachment ofthe class described which may be readily applied to and concealed withinthe overshoe, the construction providing for a removable connectionlJQU' GGD the attachment and overshoe and for the positive engagement ofthe attachment and shoe heel, whereby to prevent removal of the overshoeexcept at the will of the wearer.

The invention will be described in the following specification,reference being had particularly to the accompanying drawings, in whichFigure 1 is a view in section partly in elevation illustrating theapplication of my improved fastener, Fig. 2- is perspective of thefastener detached.

Referring particularly to the drawings my improved fastener comprises abase plate 1 designed to fit within the heel portion of the shoe, saidplate approximating in outline the interior contour of said heelportion. Near the rear edge the base is provided with a heel plate 2extending at approximately right angles to the base and designed toembrace the rear portion of the heel 3 of the shoe. The heel plate isprovided at its forward terminals with upwardly projecting arms 4, whichextend above said heel plate and are provided at their upper edges withclasp or engaging members 5, designed to receive and firmly thoughremovably secure the upper edges of the overshoe above the heel portionthereof, as will be apparent.

The base 1 is centrally and longitudinally provided with an offsetportion forming a groove way 6 in which is slidably mounted a bar 7. Atthe rear end the bar is bent up wardly about half the height of the heelplate and formed on its upper terminal with a forwardly projecting spur8 designed to register with and operate through an opening 9 formed inthe heel plate. At the forward edge the base 1 is provided with lips 10disposed on opposite sides of the guideway 6 and bent upwardly at anangle to the base plate, their free edges being rolled. or otherl wiseformed to provide bearing sleeves 11,

the formation being such as to dispose these sleeves wholly in advanceof the plane of the lips. An operating rod 12 is mounted in the sleeves11, being centrallyformed with a crank portion 13, one end of said rodbeing provided with a handle or lever portion 14- projeoting from therod in a plane on tllC crank 13 and of a length to extend to or abovethe free upper edge of the overshoe when said l ver is disposed invertical or operative position.

The crank 13 is disposed between the bearing sleeves, that is inalinement with "the guideway 6, the cross bar of said crank engaging aneye 15 formed the forward end of the slide bar 7, said eye beingpreferably an integral extension of said rod suitably bent to embracethe cross bar of the crank.

A shield 16 is preferably secured to the base 1 and disposed to overliethe guideway 6, so that the slide bar may be freely moved in theguideway without interference from the heel of the shoe.

In usewith the attachment secured to the overshoe by the clasps 5engaging the edge thereof, and the base plate 1. resting upon the heelportion of the overshoe, the lever 14 is turned toward the front of theshoe, with the effect to rock the crank 13 in the rearward direction andthereby move the spur S to its rearward limit, that is slightly beyondthe plane of the inner surface of the heel plate. The overshoe is nowapplied to the shoe in the usual manner, with the heel of the shoeresting snugly against the heel plate 2. The lever 14 is now returned tovertical or operative position, thereby forcing the spur 9 into thematerial of the heel, and serving to secure the overshoe againstaccidental removal. The overshoe may be readily removed by adisengagement of the spur 8 from the heel through suitable operation ofthe lever 14, it being noted that the concaved forward portion of theheel provides suflicient space for the necessary movement of the crank13 in the disengaging operation.

The attachment as a whole is preferably made of light steel or similarmaterial, whereby to avoid any noticeable increase in the weight of theovershoe, While at the same time providing for continued reuse of theattachment without liability of breakage or eX- cessive wear.

As the attachment is secured to the overshoe solely by the clasps 5 itis obvious that it may be quickly and conveniently initially applied orremoved when desired.

The spur 8, slide bar. 7 and crank 13 are preferably so arranged thatwhen in looking position said crank is disposed in vertical alinementwith the bearing portions of the rod 12 within the sleeves 11, therebyavoiding any tendency to dislodge the connecting medium through jar inthe use ofthe overshoe.

By preference the distance between the lips 10 and the heel plate 2 issuch as to snugly receive the heel of the shoe, so that in use theindependent movement or slip of the overshoe incident to the ordinaryconstruction is prevented, whereby the life of the shoe is materiallyincreased.

Having thus described the invention what is claimed as new, is

1. An attachment for overshoes comprising a base plate designed to fitwithin the heel portion of the overshoe, a heel plate at the rear edgeof said base plate, lips projecting from the forward edge of the baseplate, a slide bar movable in the base plate, means for operating saidbar, and means carried by said bar to engage the heel of the shoeinserted in the overshoe.

2. An attachment for overshoes comprising a base plate formed with alongitudinal guideway, a slide bar movable in said guide way, a heelplate projecting from the rear heel portion of the overshoe, projectionsat the forward and rear edges of said plate to receive the heel of theshoe between them, a slide rod movable in the base plate, means carriedby the forward projections and connected to said slide rod for operatingthe latter, and means carried by said rod and operative through the rearprojection to engage the heel of the shoe.

4. An attachment for overshoes comprising a base plate designed to fitwithin the heel portion of the overshoe, a heel plate at the rear edgeof said base plate, lips projecting from the forward edge of the baseplate, a slide bar movable in the base plate, means for operating saidbar, and a spur carried by the slide bar and operable through the heelplate to engage the heel of the shoe inserted in the overshoe.

In testimony whereof, I afliX my signature in presence of two witnesses.
